Plastic cap mold is mainly used to make plastic cap products. What is the numerical control of plastic cap mold? Numerical control is the abbreviation of digital control. That is to say, the movement parameters of the machine tool or tool are represented by digital information, which is sent to the computer, and the plastic bottle cap mould is controlled by the computer, so that the relative movement between the processed part and the tool can meet the requirements, so as to realize the processing of the part. It is a highly efficient automatic machine tool controlled by computer. It comprehensively applies the latest achievements in automatic control, computer technology, precise measurement and machine structure. CNC machine tool is generally composed of CNC system (computer and interface circuit), driving device (servo circuit and servo motor), main machine (bed, column, spindle, feed mechanism, etc.) and auxiliary device (hydraulic device, air pressure device, exchange workbench, cutter and detection device, etc.).

(1) when machining parts on the mould with high degree of automation, the whole machining process is controlled automatically by the CNC system according to the machining program. The operator only needs to press the operation button and observe whether the machining process is normal.

(2) the processing process of the plastic cap mould with strong adaptability is controlled by the program. When a part is to be processed, the processing program must be compiled according to the size, shape and technical requirements of the part drawing, and then it is sent to the computer of the numerical control system. When the object to be processed changes, in addition to the replacement of tools and fixtures, it is only necessary to write a new processing program according to the processing requirements of the new object. Therefore, the mold processing range is very wide, can save a lot of special clamps, especially suitable for single piece small batch processing.

(3) the main shaft and servo drive system with high performance, high-efficiency and high-precision transmission parts (such as ball screw pair, linear rolling guide, etc.) and die structure with high dynamic stiffness are mostly used for good processing quality and high precision. The measures of improving die wear resistance and reducing thermal deformation are taken to maintain high geometric accuracy and positioning accuracy. Because of the automatic processing of the die, the artificial operation error is reduced, so it has high processing accuracy and dimensional consistency.

(4) high production efficiency due to the high degree of automation of numerical control, the work of drawing lines, fixture design and manufacturing, multiple fixture positioning and detection are omitted in the process of processing, so the production efficiency of numerical control processing is high.

(5) it is easy to form network control, which can use a main computer to control multiple molds through the network, and can also establish a communication network between multiple molds, which is conducive to the formation of an integrated manufacturing system integrating computer-aided design, production management and manufacturing. Of course, the application of NC machining method also has the disadvantages of high mold price, complex technology, high requirements for mold maintenance and programming technology. In order to make full use of the high performance of the die and give full play to its advantages of high efficiency, a series of problems must be solved, such as the programming of parts processing program, the supply and adjustment of cutting tools, and the training of maintenance personnel. In addition, the die is not suitable for machining parts with simple shape, low technical requirements, excessive blank allowance and uneven allowance.
